Authenticator question

Hey. My phone recently broke and it has my authenticator on it, so I've not been able to play WoW. I have 2 WoW accounts on my battle.net account, I was wondering if the authenticator applies to the whole battle.net account, or just my WoW1 account? I'm not looking to remove it or anything, it will only be a problem for a few days.

This happened to me a couple of months ago. They'll probably ask you to take a pic of some ID and attach it to a ticket so they can verify it's you. If you have everything ready before you call, it shouldn't take more than 3-4 mins once you get through to them.
